Answer:

31.77 yd/sec

Step-by-step explanation:

<u>Conversions:</u>

  • 1 mile = 1760 yards
  • 1 hour = 3600 seconds

<u>Given:</u>

\sf 65\:miles\:per\:hour=65\:miles/hour=\dfrac{65\:miles}{hour}

Therefore, to convert 65 mph to yards per second:

\implies \sf \dfrac{65\:miles}{hour}=\dfrac{65 \times 1760\:yards}{3600\:seconds}=31.777...\:yd/s

Answer:

c.) 31.77... yd/sec

Explanation:

Given: 1 hours → 65 miles

Conversions:

(i) 1 hour = 60 minutes = 3600 seconds

(ii) 1 miles = 1760 yards

Then,

  • 1 hour = 3600 seconds
  • 65 miles = (1760 × 65) = 114400 yards

<h3>  Speed:</h3>

⇒ distance/speed

⇒ 114400/3600

⇒ 31.77777...

⇒ 31.77 yd/sec

Answer:

A. 60°

Step-by-step explanation:

There's a very straight-forward explanation for this, thank god! XD

For this type of problem, there's a rule to follow for the outside angle. X and 120 should equal 180, so all you need to do is fill that gap.

180-120 = 60

60 is your answer because it completes the whole angle.

The graph shows the altitude, a, of a plane, in feet, after t minutes. What is the rate of ascent of the airplane?
alexira [117]

The rate of ascent is also known as the slope. To find the slope, we will follow the steps below.

Step 1) Choose two points on the line

Point 1: (4, 500)

Point 2: (8, 1000)

Step 2) Use the slope formula to find the slope

m = (y2 - y1) / (x2 - x1)

m = (1000 - 500) / (8 - 4)

m = 500 / 4

m = 125 feet per minute

Hope this helps! :)
